浮动操作按钮throing错误
我真的不知道为什么我的程序没有执行。我觉得我做everythink这里解释:FloatingActionButton example with Support Library浮动操作按钮throing错误
my_layout.xml
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/fab_margin"
android:src="@android:drawable/ic_dialog_email" />
</android.support.design.widget.CoordinatorLayout>
gradle这个:
apply plugin: 'com.android.application'
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
compile project(':appcompat_v7')
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
}
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}
添加@色/ floating_action_button_color到\应用程序数据\本地\的Android \ Android的SDK \平台\ android-22 \ data \ res \ values \ themes.xml
但是执行程序后总会出现这样的错误:

任何想法如何解决这一问题?谢谢。
确定....我切换到Android工作室...哇一切工作。
您的MyLayoutActivity
应扩展AppCompactActivity
而不是ActionBarActivity
。
对不起,我忘了写“我的_”......它在eclipse中是正确的......改为AppCompactActivity ..但仍然是一样的错误。 – h0ppel
@ h0ppel现在尝试重新启动重建项目 – jayeshsolanki93
没有改善:( – h0ppel
你能发布MyLayoutActivity的代码吗? – jayeshsolanki93
错误是:没有找到类“android.support.design.widget.CoordinatorLayout”。尝试再次同步您的build.gradle并重建项目... – W0rmH0le
清理您的项目并重新启动。 – jaibatrik
